I was at a friend's house recently and she showed me a quilt in a bedroom that she called her "grandmother's room". It had vintage furniture, lamps, etc..... a lot of things from her parents and grandparents era that were passed down to her. On the bed was a yo-yo quilt. Her grandmother had taken yo-yo's and sewed them together. Looked like just a few whip stitches that you could see on each "side" of the yo-yo. It was on a double sized bed and she had a white sheet under that showed thru between all the yo-yo's. It was stunning. The fabric was very interesting to examine. Probably a lot of old flour & sugar sacks. Good luck and let us know what you do with it.
